Zomato founder and CEO Deepinder Goyal turned heads during his recent appearance on popular podcaster Raj Shamani’s “Figuring Out” show, not just for his candid insights on entrepreneurship and Zomato’s journey, but for a sleek silver device visibly attached near his eye. The unique accessory was later revealed to be Temple, an innovative experimental wearable designed to monitor brain blood flow in real time.
The episode, which was released on January 3, 2026, quickly went viral, with viewers zooming in on the small gadget positioned on Goyal’s temple area. Social media buzzed with speculation, leading to widespread coverage of the device, which marks Goyal’s ambitious foray into health-tech – something that went beyond his food delivery empire.
What is Temple?
Temple is a lightweight, daily-wearable sensor developed under Goyal’s ventures, including Eternal (Zomato’s parent company) and Continue Research. Described by Deepinder Goyal as an “experimental device to measure Brain Flow precisely, in real-time, and continuously,” it tracks cerebral blood flow, a key biomarker linked to neurological wellbeing, cognition, ageing, and longevity.
The gadget, which often appears as a compact silver or gold clip near the temple, uses advanced sensors (potentially with AI integration) to provide continuous data on brain circulation patterns. This could offer users actionable insights into:
– Focus and mental fatigue for students and professionals.
– Stress responses and emotional regulation.
– Cognitive decline in the elderly.
– Optimisation for athletes or high-performers
Inspired by Goyal’s personal research into the ‘Gravity Ageing Hypothesis’ — the idea that upright posture and gravity subtly reduce brain blood flow over time, accelerating ageing — Temple aims to test and validate such theories through everyday monitoring.
Goyal has been personally testing the device for over a year, calling it a tool for preventive health in a world where “staying healthy is hard” and time-consuming.
From podcast to health-tech
While the wide-ranging podcast covered topics like Zomato’s near-bankruptcy in 2020, co-founder exits, and delivery challenges, the unobtrusive yet noticeable Temple stole the show. This public debut aligns with Goyal’s earlier teases in December 2025, where he shared images and described Temple as “world-class” progress in unexplored consumer wearables. No official launch date, pricing, or full specs (like battery life or app integration) have been announced, but early-access or a limited rollout is anticipated.
